help with multiple input?

i got the solution:

in the model this must go:

Code:

// Check to see if there is more than one car
if ( count($data['cars']) > 0 ) {

for($i = 0; $i < count($data['cars']); ++$i) {
$this->CarModel[$i]->car = $data['cars'][$i];
                    
        }
                
    }
// If only one car then
else {
$this->CarModel[0]->car     = $data['cars'];
}
